The use of silvicultural hot spots to increase the intensity, forest management resistance and resilience of Golišče forest
No full textGozdnogojitvene vroče točke so del gozda, kjer je učinkovitost gozdnogojitvenega ukrepanja v smislu doseganja ciljev gospodarjenja z gozdom večja kot v okolici. Ker so dober pripomoček, ki lastniku prikaže v kašnem stanju je gozd in kakšne so možnosti za nadaljnji razvoj smo analizirali 6 vročih točk na parceli na Goliščah, kjer je potekala raziskava. Cilj vsake točke je bil pospeševanje proizvodnje kakovostnega lesa. Na vsaki točki smo popisali drevesa v zgornji drevesni plasti po Bitterlichovi kotnoštevni metodi. Na vsaki ploskvi smo popisali tudi dve ploskvi mladja velikosti 5 x 5 m. Analize so pokazale, da se na vseh ploskvah mladja drevesne vrste dobro pomlajujejo. Največji delež dreves v zgornji drevesni plasti, pa predstavljata kostanj in smreka. Vsaki točki smo po analizi postavili gozdnogojitveni cilj in ji določili prioriteto ukrepanja, ter ukrepe za doseganje cilja. Na podlagi analiz in postavljenega cilja predlagamo ukrepanje za pospeševanje drevesnih vrst, ki so za lastnika najbolj primerne za prodajo. Z določitvijo točk smo, v primerjavi z gozdnogojitvenim načrtom, dosegli natančnejše informacije o trenutnem stanju sestoja in prostorsko bolj natančno opredeli ukrepanje.Silvicultural hotspots are a part of the forest where the effectiveness of silvicultural measures in terms of achieving forest management goals is higher than in the surrounding area. Since they are a good tool to show the owner what the condition of forest is in and what are the possibilities for further development, we located 6 hot spots on the plot in Golišče, where the research took place. The goal of each point was to promote the production of quality wood. At each point, we listed the trees in the upper tree layer according to the Bitterlich angular method. On each hotspot, we established two plots for regeneration measurements, 5 x 5 m in size. Analyses on these plots have shown good natural regeneration in all locations. The predominant tree species in the upper tree layer were chestnuts and spruce. After the analysis, a silvicultural goal and priority level is set for each hotspot. Based on our analysis, we suggest tending measures to promote species that are most suitable for the owner in terms of market value. Hotspots give additional information, in comparison to silvicultural plan, about the present stand conditions and more spatially defined information about the location of the prescribed silvicultural treatment
Monitoring assisted migration success of transplanted oak seedlings in beech dominated forests
No full textV raziskavi smo izvedli umetno obnovo s puljenkami treh vrst hrasta: gradna, cera in puhastega hrasta na različnih pretežno bukovih rastiščih. Namen metode je bil ugotoviti, ali bodo drevesne vrste, ki izhajajo iz drugačnih podnebij kot mesta saditve, zagotovile uspešno obnovo gozdov z možnostjo prilagajanja. Poleg tega nas je zanimalo še, ali bo delež preživelih puljenk hrasta večji na boljših rastiščih. Metodo dela smo razdelili na tri faze: 1.) izbor semenskih sestojev (vir puljenk), 2.) puljenje in saditev in 3.) opravljanje prve meritve. Od vsake vrste smo napulili 300 puljenk. Saditev puljenk je potekala na treh lokacijah: na Vrhniki zgoraj, Vrhniki spodaj in v Goliščah. Sadili smo na ploskve v obliki trikotnika, velikosti 2 × 2 × 2 m. Znotraj vsakega trikotnika smo posadili 10 puljenk vsake vrste. Vsak trikotnik je vseboval 30 puljenk hrastov. Na vsaki lokaciji smo naredili 10 trikotnikov tako, da je imela vsaka lokacija skupaj 300 puljenk – 100 gradna, 100 cera in 100 puhastega hrasta. Meritve ploskev in osebkov so bile opravljene znotraj QGIS paketa. Obdelava podatkov je potekala v Microsoft Office Excelu, JASP-u ter v R programu. Meritve so pokazale, da je v prvi vegetacijski sezoni po saditvi preživelo več kot polovico vseh puljenk. Najbolj uspešni vrsti v preživetju in rasti sta bili cer in graden, puhasti hrast pa je bil bistveno manj uspešen. Razmere za preživetje in rast vseh puljenk so bile najboljše na Vrhniki spodaj. Preživetje je bilo najslabše na Vrhniki zgoraj, pogoji za rast pa v Goliščah. Prav tako nam ni uspelo dokazati, da je delež preživetja puljenk večji na boljših rastiščih.In the research, we carried out artificial regeneration with transplanted seedlings of three types of oak: sessile oak, turkey oak and downy oak in different predominantly beech habitats. The purpose of the method was to determine whether tree species originating from different climates than the planting sites will ensure successful restoration of forests with the possibility of adaptation. In addition, we were interested in whether the proportion of surviving oak seedlings would be higher on better sites. The work method was divided into three phases: 1.) Selection of seed stands (source of transplanted seedlings), 2.) Pulling and planting and 3.) Performing the first measurement. We pulled 300 seedlings of each tree species. The planting of the seedlings took place in three locations: on Vrhnika above, Vrhnika below and in Golišče. We planted on plots in the shape of a triangle of size 2 × 2 × 2 m. Inside each triangle we planted 10 seedlings of each species. Each triangle contained 30 oak seedlings. At each location, we made 10 triangles so that each location had a total of 300 transplaneted seedlings – 100 sessile oak, 100 turkey oak and 100 downy oak. Measurements of plots and seedlings were made within the QGIS package. Data processing took place in Microsoft Office Excel, JASP and R program. The measurements showed that more than half of all the transplanted seedlings survived in the first growing season after planting. Turkey oak and sessile oak were the most successful in terms of survival and growth, while downy oak was significantly less successful. The conditions for the survival and growth of all transplanted seedlings were the best on Vrhnika below. Survival rate was the worst on Vrhnika above and growth conditions were worst in Golišče. Also, we were unable to prove that the survival rate of transplanted seedlings is higher in better habitats for neither of the tree species
Institutionalizing ASEAN: celebrating Europe through network governance
No full textThis article provides a new piece for two of the puzzles of institutionalized cooperation in Association of Southeast Asian Nations (ASEAN). First, with regard to the organization's four decades of existence, there has always been a marked gap between ASEAN's rhetorical goals of cooperation and its actual achievements. What explains these systematic failures of implementation? Second, from the outset, ASEAN was criticized for its light institutionalization, which failed to deliver the substantial cooperation goals. Despite selected institutional reforms, ASEAN's autonomy has not increased remarkably and it has not made any major institutional innovations. Why does ASEAN design institutions it does not use? Why does this transformation gap occur? The author suggests a sociological institutional explanation and argues that major impulses for cooperation have come from outside Southeast Asia, most importantly from Europe. By mimicking the European integration process, ASEAN member states have effectively created an isomorphic organization. The Association's institutional development reflects a concern for international legitimacy and less an objective functional demand arising from the specific interactions of member states. This copying process has led to network governance within the organization

Smart coatings for corrosion protection of the construction materials
No full textKorozija povzroča degradacijo kovinskih materialov, ki so v stiku s tekočino ali plinom. Sam proces se pospeši z izpostavitvijo visokim temperaturam, kislinam in solem. Posledično se spremenijo lastnosti materiala in nastaja škoda pri samem tehnološkem procesu. Da bi korozijo upočasnili, uporabljamo različna inhibitorna sredstva, ki so lahko organske ali anorganske narave.
Diplomsko delo prikazuje študijo pametnih prevlek kot zaščito pred korozijskimi procesi na kovinski površini. Prevleka vsebuje inkapsuliran inhibitor, ki se sprosti, ko se nahaja v agresivnem okolju. Njegovo delovanje lahko zapolni poškodbe na prevleki, ki nastanejo ob fizični poškodbi, ob spremembi pH na medfazni površini med prevleko in korozivnim medijem ter podobnim. Ovojnica kapsule se ob tem predre, sprošča se inhibitor, ki se običajno adsorbira na površino in na tak način nudi dodatno zaščito pred korozijo.
Uporabili smo vzorce iz aluminijeve zlitine tipa EN AW 6451 in jih predhodno obdelali tako, da je bila oprijemljivost prevleke iz epoksidne smole z inkapsuliranimi delci inhibitorja čim večja. Zaščitni sloj smo nanesli z metodo \u27spin coatinga\u27, ki ustvari enakomerno tanek sloj zaščitne prevleke na površini preiskovanega vzorca. Testirane prevleke so vsebovale tri različne koncentracije inkapsuliranih delcev inhibitorja. Največjo inhibicijsko učinkovitost je imela \u27pametna prevleka\u27 z najvišjim utežnim odstotkom inkapsuliranih delcev, ki so vsebovali kationski surfaktant. Za korozivni medij smo uporabili vodno raztopino natrijevega klorida z dvema različnima koncentracijama (3,5 % in 0,1 mol/L). Meritve smo izvedli na vzorcih po 30-minutni stabilizaciji v raztopini na mirovnem potencialu in po 48 urni predhodni izpostavitvi korozivnemu okolju. V posameznih primerih smo dosegli tudi najvišjo možno vrednost inhibicijske učinkovitosti in sicer = 99 % - 100 % .Corrosion presents a process that causes degradation of metal, when it comes into contact with liquid or gases. The process accelerates with exposure to high temperature, acidic solvents and salts. Chemical deterioration of a material leads to technological problems. Therefore, various inhibitors (organic or inorganic) are used for corrosion protection.
This thesis presents the study of smart coatings for corrosion protection of metal materials. The coating contains an encapsulated inhibitor, which is released in contact with the agressive medium. Its activation can fill the gaps on the surface coating. The flaws in the coating can be caused by many factors, e.g. a physical injury, changed pH at the contact of the metal with the corrosive environment. Nanocapsules are able to detect active corrosion and release the inhibitor that increases corrosion protection.
Aluminium based metalic substrates (EN AW 6451) were used in the experiments, which were previously processed for better adhesion of epoxy coating with nanocapsules containing the corrosion inhibitor. Spin coating was employed to apply the smart coating onto the metal surface. Tested coatings were prepared using three different concentrations of encapsulated cationic surfactant. The best inhibition efficiency was exhibited by the smart coating with the highest mass fraction of nanocapsules within the mixture. A water solution of sodium chloride with two different concentrations (3,5 % and 0,1 mlol/L) was used as corrosive medium. Tests were performed after 30 minute stabilisation of the sample in the solution and after 48 hour exposure to the corrosive environment. The applied smart coatings show a high potential fort he use as an efficient corrosion protection
Discussing Anja Štefan`s fairytales in the first year of primary school
No full textFairytales are an indispensable part in children's lives. They stimulate the development of imagination, fantasy; they help to enrich children’s vocabulary and with expressing feelings. There are different types of fairytales and it is very important that children get to know the variety of them. I firstly presented a youth author Anja Štefan and her literary works in my diploma paper. Later on I continued with the presentation of youth literature and I defined the theory of a fairytale, wrote about the origin, its meaning and classification of fairytales which I have also described in greater detail. I stated and described authorial prose work of Anja Štefan: picture book Lešniki, lešniki and classic fairytales Kotiček na koncu sveta, Melje, melje mlinček and Štiri črne mravljice, which can be defined as animal fairytales. I was interested in the receptive development of children in the period of intuitive intelligence, which I thoroughly described. In the empirical part of my diploma I wrote lesson plans for discussing and teaching three Anja Štefan’s animal fairytales in the first grade of primary school. 25 children took part in the research. I found out that pupils distinguish between real and unreal life (imaginative life), they are capable of identifying themselves with a literary person and they perceive animals as literary persons and they identify themselves with them
